eclipse kepler "Cannot install remote marketplace locations"

I have downloaded the latest eclipse version, eclipse kepler.

But when i try to access the Marketplace inside eclipse or try to install ADT plugin for Android, it gives me this creepy error which is driving me crazy:

Cannot open Eclipse Marketplace
Cannot install remote marketplace locations: Connection failed

  • I figured out finally that:

    Avira Anti-Virus Software was blocking the network requests by eclipse. After deactivating "enable web protection" in the Anti-Virus, the stupid Eclipse was able to update itself.
